IMPROVD `EXTENSIONTABLE The Schedule referred to in these Letters Patent and making part cf the same.

To all whom. it may concern:

Be it known that I, CHARLES P11. Lnsz, of Poughkeepsie, in the county of Dutchess, and State of New York, have invented a new and useful Improvement in lilxtension-Tables; and l (lo hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make. and use the sa1ne,reierenue heilig had to the lecompanying drawings, ibrming part. ot' this specification.

This invention relates to new and useful improvements in extension-tables, and consists in the construction and arrangement hereinafter described.

In the accompanying plate of drawings- Fignre l represents the table extended, with the filling removed.

Figure 2 is a view with the filling in place.

Figure i is a cross-soction ot' l, through the line a' Figure 4 represents a cross-section oi' the extensionrails, and the method ot' forn'ling the grooves and tongues.

Similar letters ot' reference indicate corresponding parts.

The tongues and grooves of the extension-rails of this table are formed of metal plates, as seen in tig. 4, where A represents the rails, B, the groove-pieces, and (l, the tongue-pieces.

These pieces, yB and C, are made ot' metal, and may be rebated or set out from the rail, by intervening strips, so as to t'orm tongues and grooves, as seen in the drawing. Forming the grooves and tongues by means of metallio plates, as represented, allow the rails to freely slide back and forth.

The shrinking, swelling, or warping of the rails does not interfere with thc proper working of the table, while, by this arrangement, the space `usually faken up by the rails of an extension-table is so much reduced that ample room is left between them'for storing the iilling when the table is not extended.

D, E', and F represent the sect-ions or filling of' the table.

lhese pieces do not diii'er materially from those of ordinary extension-tables, only each section is made in two parts, which are hinged together for the purpose of reducing their length by doubling the. parts together when they are packed away, as seen iii fig. 3, between the rails. v

lft will be seen that the. sections are not only doubled together when the table is extended, as seen in iig. 2, but hooked together, as seen at G, with extra dowelpins, as seen at H, for supporting the joint I of' the separate sections. `l

By this arrangement and formation of the table, I obtain sutlicient space between the rails for storing the iilling where it is entirely out of sight, and out oi' the way when it is not in use. This of itself is a very important consideration, as with the comnion extern sion-table a separate box or rack must be provided for it.

By the use of metallic plates tor forming the tongues and grooves, the shrinking andrswelling,- o1' warping of the rails does not ati'ect the proper working of the table. lWere the sections 1),]9, and F (orilling of the table) made each in a single piece, as is usual, they could not be packed away, as seen in tig. 3, when the semicreles J K were closed up, as their ends would project beyond the circle formed. ,By making the joint I, this obstacle is overcome.

The advantages of this arrangement will be understood and appreciated by all who are acquainted with the common extension-table.

Having thus described my invention,

l claim as new, and desire to secure by Letters Patent- The combination of rails A, A, metallic grooves B B, and tongue,-with sliding extension-frame, hinged detachable leaves, and the receptacle for said leaves, all of said parts heilig arranged with respect to each other in the manner specitied.

The above specilication of my invention signed by me, this 12th day otJnly, 1869.

CHARLES PH. LFUZ.
